An agitator or baflle (3 1s application above noted. Angle bars 14, 15, pivoted to and carried by nner ends of the 16 and 17are arranged side by side in steeply arms 72 and occupies a posit-ion parallel with,

gear 68- on the shaft 45. Angle bars 69, '70 "loo 1 slightly spaced from and in front of the.

snapping roller 59, said agitator being :in. oneend thereof. together with a cap 76 securedthereto and is adapted to receive and journal the upper end portion of the snapping roller 58 or its shaft. A bearing 77 is mounted in a slide seat in the opposite end of the block 75 and is confined by a cap 78 mounted on saidblock opposite to the cap 76, a compression spring 79 being interposed be- .tween the capi78and the bearing 77. The 7 upper end portion of the snapping roller 59 or its shaft is journaled in the bearing-77.

A similar cushioned bearing isprovided in oneof the bearings 60 to accommodate the lower end of. the roller 58. Thus provision is made for yieldingly mounting oneo'flthe snapping rollers to compensate for. an overload occasioned. by pass ng between them of cornstalks or other objects. In Figure 6 the snappingrollers 58, 59 are shown-in detail in cross section. The roller 58 isshowniwith arcuate-spiral grooves 80in itsperi'phery,-

each of said grooves formingiedges 81; The roller 59 .is shown with opposite spiral grooves 82, the portions. 83 of the periphery 7 between said grooves'being on right lines 8O.w The snapping'rollers 5'8, 59have-been' having outward curves between them. and

forming edges at the sides of-the grooves 82.

corn' 'stalks are accommodated inthe gr'ooves described as inter-connected through .the spur-gears 61, 62, whereby they a'redriven in unison, and the intermeshing of said spurgears is deep enough to compensate for any sprlngmg apart that may be occasronedby corn-stalks-passing betweenthe rollers, it be-- Ling-understood that only the smaller upper portionsof the corn-stalks pass between said rollers in proximity to the spur-gears.

ever, the rollers dospring apart to permit the corn-stalksto pass between them under the effect of the oppositely rotating rollers and the edges 81 of one roller .coact with the grooves 82 vof the other roller to pinch: and

sever the stems of the ears from the stalks, .thus snapping the ears, husks, from the stalks,

generally with their How- In practical use the shaft 45 serves as a driver and, acting throughthe shafts and rollers asabove described and the tumbling rods rotates themoppositely in such manner as to involutely drive thesnapping rollers 58,

'59 and tumbling rods. It isthe function of the snapping rollers, to v snap the ears from thestalks and" the ge'arratio employed is such that all of thestalks andforage thereon is y left in the best possible condition after it has passed between the rollers.
